Vintage Givenchy Nouvelle Boutique Short Sleeve Button Down Blouse

Vintage Givenchy Nouvelle Boutique Short Sleeve Button Down Blouse. Sleeves have pleats with contrast fabric. Gray and white. Fabric tag is missing but it appears to be polyester and rayon or maybe just rayon. Fabric has no stretch. Fabric feels almost like a crepe material Size: Small (tag is missing but I am a Sz S and this fits like a small) Approx measurements: Armpit to armpit: 18” Length: 25” Pre-owned, good condition but note the following: left sleeve has a slight small darker spot where the solid and polka dot fabric almost meet. Also on the polka dot strip there is a fabric run that is very hard to even notice and one small dot appears to have a very tiny mark. Then bottom hem appears to ge hand stitched and I am not sure why. This is shown in the photos
